Continuity mistake: In the scene where William Fichtner is shown first leaving his trailer and picking up litter in the amusement park, his gloved hand switches from his right hand to his left then back to his right again before he starts talking to the couple. (00:05:40)
Continuity mistake: When Phoebe is left alone at the couch, her mom comes up to talk to her. Before her mom shows up, there is a water bottle in front of Phoebe. After Phoebe's mom sits down next to her, the water bottle moves to the other side of the table without anyone touching it.
Continuity mistake: Right at the beginning of the episode a Cadillac Escalade gets stolen. The car is the newest model. The chase begins and the car is a new model right up to a scene when they crash into some other cars. That part was filmed with older model Cadillac. The damage is quite severe, but the chase continues again with the new model that has only one bit of damage - a mirror that has come apart.
Continuity mistake: Near the start, the camera pans out to see the dome now covered in a layer of black. Outside of the dome you can see nice green fields, a small forest area, little houses and everything looks rosy. However a few episodes back the military launched a MOAB (mother of all bombs) and and the surrounding area was wiped out completely. (00:05:50)
Continuity mistake: In Season 1, Episode 5, we see the MI5 agents report Sam and Phil's identities to the Director. With the ID cards on screen, they state Sam as being 29, with a date of birth 25/03/1983. The series was released in 2013, so this age fits with the show's production dates of late-2012 or early-2013. However, Phil's age is described as 31 (but DOB is visible as 11/09/1985 - which would make him 26 or 27). Phil's age is detailed as 31 elsewhere in the series. (00:01:25)
Continuity mistake: In one scene, Claire Underwood is returning to the White House from Iowa. In the hallway leading to her bedroom's stairs, she is followed by a black female Secret Service agent, obviously part of her entourage, who stops to stand guard at the beginning of the stairs. In another scene 30 minutes later, that same agent is seen standing guard at the entry of the campaigning house in which Frank Underwood is going to say his victory speech. But Claire has not flown from Washington to Iowa, so the agent should not be there. (00:15:15 - 00:45:30)
